Answer:
Option C
Explanation:
Let the potential energy of rock A be represented as Pa
And the potential energy of rock B be represented as Pb
Pa = ma * g * h
Pb = mb * g*h
ma = 2 * mb
Thus, Pa = 2 mb * g*h
Pa/Pb = 2 mb * g*h/mb * g*h
Pa/Pb = 2
Pa = 2 * Pb
The energy pf rock A is two times the energy of rock B.
OR
Pb = Pa/2
Hence, option C is correct

Answer:
<h3>He needs 5 more months of savings for him to reach his goal. </h3>
Explanation:
Given the equation that models Damon's saving plan as y = 500 + 400x where x represents the number of months since last week and y represents the total amount he's saved for the vacation. Since he estimates that he'll need about $2,500 for the trip, therefore y = $2,500.
In order to determine how many more months of saving (x) it will take to reach his goal, the following steps must be taken by Damon (Damon true statements)
Step 1:
y = 500 + 400x
Step 2: Subtract 500 from both sides
y - 500 = 500 + 400x - 500
y-500 = 400x
Step 3: Substitute y = $2500 into the resulting equation and solve for x
400x = 2500-500
Step 4: Take the difference of the value at the right hand side of the equation
400x = 2000
Step 5: Divide both sides by the coefficient of x (i.e 400)
Step 6: Get the value of x
x = 5
complete question;
distinguish between culture and society then identify three factors that influence cultural change.
Answer:
The most common definition of culture is that it is a way of life. It is a way of life of a particular group of persons that is passed down from one generation to another generation.
we can also define the word society as group of persons that live together in an ordered community. The people in a society could share same beliefs as well as have common interests. A society is also a combination of different persons that are of different cultures.
The main difference between society and culture is that while the society comprises just of the people who share same beliefs and practices, culture is the beliefs and the practices of this people.
several factors are responsible for cultural changes in a society. three of these influences are:
- <u>contact: </u> When two societies come in contact with each other, there is likely to be a change in culture of both societies. This is known as cultural diffusion (the spread of cultural belief from one society to another society).
- Evolutionary changes in technology: Any form of advancements or evolutions in technology could bring about changes in culture. Technological evolution in production technology or changes in means of transportation and communication could influence cultural changes.
- Geological and ecological influences: These are factors that influences cultural changes. An example is rainfall, altitude, proximity to sea.
These factors are all capable of deciding the culture as well as the lifestyle of dwellers.
